' ENGLAND a DEVICE FOR REMOVING THE VALVES FROM INTERNAL-COMBUSTION EIYI'GILTES Application filed July 18, 1928, Serial No. 293,757; and in GreatBritain August l6, 1927.

In connection with the cylinders of internal combustion engines and especially of those wherein the Cylinders are arranged to be vertical or inclined and with the, valves situated in the head of the cylinder, considerable diificulty is experienced in removing the Valves from their positions or seatings to carry out the necessary cleaning and repair-q mg of same. My invention consists in the production of means whereby, after the cylinder-head has been removed from the cylinder my improved devices may be applied to said,

head and made use of for removing the valves therefrom in a more expeditious manner than heretofore thus the process of cleaning and carrying out repairs is greatly facilitated.

In order that my said lnvention may be readily understood I have hereunto appended sheets of drawings illustrative thereof to which by figures and letters reference is made in the following description Fig. 1 is a plan of a cylinder head showing the application of my improved devices.

Fig. 2 is a sectional elevation of the parts shown by Fig. 1 and with my devices shown in position prior to commencing the compression of the spring.

Fig. 3 is a similar view to Fig. 2 but shows only one valve and with my devices in posi 50 tion when compressing the spring.

Fig. 4 is a plan of the valve spindle and the plate or washer which takes over the end of the spring.

Fig. 5 is a plan showing the formation of the several parts of my improved device.

Fig. 6 is an. elevation of the parts shown by Fig. 5 said parts being shown in their respective positions as when used on a valve spindle which is at an angle to the axis of the cylinder as shown by Figs. 1, 2 and 3.

Fig. 7 is a similar view to Fig. 6 but shows the positions of the parts when the axis of the valve spindle is parallel to the axis of the cylinder.

In carrying my invention into eflect I make use of a base member 2 which is formed to fit against the detached head 3 of the cylinder as shown by Figs. 2 and 3. The head of the screw 4: may be gripped by the jaws of a 50 vice in order that the head 3 and the base through the slot '6 and then be turned into member 2 may be'firmly held in position. Upon the said member or plate 2 I secure a block 5 by means of the screw 5' so that the upper surface aof this block 4 (inxthe arrangements shownby Figs. 2; 3, 4 and5) is inclined to the axis of'the cylinderbut'is at right angles to the axis'of the valve spindle 6.

The base member 2 has its. outer end 2 formed so that a slot 5 may be made therein in order that a detachable arm 7 may be inserted so position to enable its notches 7 to span or take over the two side parts of'the slot Z2 as shown by Figs. 2 to 7 inclusive.

This arm has a series of holes or openings 0 formed in it'so that a pivotal pin 8 may be inserted in any one of same to suit the requirements of the hand lever 9 when this is being used in'connectionwith a smaller or larger cylinder head 3as will be understood.

Pivoted upon the pin 8 (which is detachable) is a lever 9 in which are also made openings d for the pin 8 so that the said lever 9 may be adjusted according to the requirements of any particular size of head in connection with which it may have to be used.

The hand'lever9 has at its opposite end to its handle a bifurcation? which will span the spindle6'of the valve 6 and will reach over the annular member or washer 10 which takes over said spindle 6 V This washer or annular member 10 is of well'known formation and is held'upon the spindle 6 of the valve 6 by the coupling bush 11 taking into a groove 6 in said spindle 6 which is also of well known formation.

The bush 11 is made in halves so that it may be detachable from the groove 6 in the spindle 6 when the annular member 10 is forced down over said spindle 6 by the lever 9 and as shown by Fig. 3. This action of the lever 9 compresses the springs 12 in order that same may be held clear of the divided bush 11 as shown by Fig. 3 in order that After the removal of the divided bush 11 the hand lever 9 may be released so that the springs 12 are freed and (after the base 2 has been removed from the jaws of the vise) the valve 6 may be taken from the head 3 by withdrawing the spindle 6 of said valve after removing all the parts from the vise.

Incases where-the valves 6 andtheir spindles 6 are parallel to the axis of the cylinder in ponnection with which they have to operate Ithen make use-of a block 5 which is at right angles to the axis of the spindle 6 With .Which itv has to operate and in such case I'then turn the bar 7 with the lower end shown by Fig. 6 wherein thenotches 7 are formed so that said bar may have its notches 7* brought through V the slot 6 of the base member 2 as shown by Fig. 7 the operations ofithe other partsbeing the same as is heretofore described. As is hereinbefore ex- ;plained the divided bush 11 is of wellknown OOIIStIHCtlOH and is used inconnection with V i the annular member 10 :for readily fixing same upon the spindle 6 oft-he valve 6*, said spindle being actuated by the oscillating arm :12 in well known -manner.

The-slot cc (Fig. 5) which is made in the member 2 enables the adjustment oftheblock 5 in anyposition that alarger or smaller head 3 may necessitate.

"Such being'the nature of my said invention what I claimis In devices forcremoving valves for internal combustionengines, a basepiece'having vadjusting slots as described, a block mounted to be adj 'usted alongone slotpa lever-support formed to be adjusted along the other slot fin the base piece, said lever-.supporthaving a:series of openings formed-in it to permit the adjustment of the hand lever thereon, a "hand lever having bifurcations at one end and a handle at the other end with asseries of pivotal openings to permit the adjustment of said .hand lever andmeans for pivoting said lever upon its support.
